I'm not sure why this isn't working for you. It is outside of the domain of X
or the X driver, though.

This indeed means that no ROM is found.

This enables to ROM. It doesn't mean that you will be able to read it out.

Don't do this! This enables the card. Thus the Xserver will assume it's primary
and won't POST it any more.

Not sure why you are seeing this. It's probably due to a non-POSTed card.

That's what I also assume.
I don't think what you see are driver issues.
But in any case part of the PCI magic you did caused the second card to not be
POSTed.
Please retry and reopen in case there are still problems.
